A student wants to make 125 mL of a 0.050 M beryllium chloride solution. a) Calculate the number of grams of beryllium chloride necessary to make the solution.

b) Describe, in detail, how would you make this solution using the appropriate equipment.

c) After the student made the solution, he mixes it with a 2.5 M Pb(NO3)2 solution. Write the net ionic equation for this reaction.

i think it is true since you can test the answer and can use observations to complete it.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
